No successful non-surgical embryo collection has been reported in pigs so far,except the studies of Kobayashi et al. [50]and Hazeleger et al. [41] following surgical resection of uterine horns. The majorreason of this restriction is the anatomy ofthe porcine genital tract. Therefore embryocollection can be performed in vitro byflushing the genital tract after slaughter, butthis technique has the limit to use donorsows only once. Embryo recovery in swineis usually accomplished surgically undergeneral anaesthesia, with the genital tractpresented through a midventral incision inthe caudal abdominal region involving retrograde flushing of the oviducts and/oruterine horns [10, 24, 36, 97]. The disadvantage of surgical procedures can be diminished by minimal-invasive endoscopic techniques to recover embryos [3, 15, 90].
